The unique Astro 320 dog tracking system from Garmin pinpoints your dog's position and shows you exactly where he is on a vivid color screen, even when you can't see or hear him. The Astro system includes the Astro 320 handheld and the rugged DC 50 transmitter collar with an orange polyurethane strap (accessory color straps sold separately). DC 50 features top mounted GPS and GLONASS receivers and a newly-redesigned steel VHF antenna. Switching to rescue mode reduces the refresh rate in order to preserve battery life, giving you more time to look for a lost dog.

The Astro 320, compatible with any DC-series transmitter, also has enhanced map drawing capabilities, BirdsEye Satellite Imagery compatibility (subscription required), vibration-based alerts and a 3-axis electronic compass. Astro 320 has a microSD card slot so you can load TOPO U.S. 24K maps for land elevation contours or City Navigator NT map data for turn-by-turn routing on roads. Astro 320 also supports BirdsEye Satellite Imagery (subscription required), that so you can download satellite images to your device and integrate them with your maps.

After you've captured your quarry, mark the exact spot with Astro's Covey Counter, a special waypoint that tells you the exact location, time of day and elevation where you found your prey, as well as the number of birds you flushed and took from that location. Take charge of your next adventure with BaseCamp, software that lets you view and organize maps, waypoints, routes, and tracks. This free trip-planning software even allows you to create Garmin Adventures that you can share with friends, family or fellow explorers. The all-new BaseStation lets you turn your laptop (loaded with BaseCamp) into a field control center for tracking multiple dogs (additional DC 50 collar units required). View real-time GPS/GLONASS information on the larger display of your computer, making it ideal for canine search and rescue teams. And because it's Garmin GPS-based, safer, more effective tracking is possible, even where Internet and cell phone service aren't.
